Airflow Management

Airflow Management Blanking Panels promote proper airflow within an enclosure by occupying unused rack space. These modular tool-less blanking panels allow for quick and easy installation into any EIA-310 19 inch rack or enclosure with square mounting holes. Brush strips provide a barrier to airflow, while allowing cables to be passed from the front to the rear of the rack. KoldLok grommets seal a variety of cutouts in a raised floor environment to reduce bypass airflow and improve cooling efficiency.

Sizing and run time calculators are based on Watt ratings. VA (Volt-Amp) ratings are also a common method for measuring power but provide less accurate results. On APC.COM, VA values are often shown for convienience and may be entered as input data. However, VA values are always translated into Watts. This translation is done using an approximation formula which assumes that low VA loads have a power factor of around 0.6 and high power loads have a power factor of nearly 1.0, which is representative of typical, (but not all) computing equipment. For highest precision, use Watt values where available.

The translator below shows how VA can be converted to Watts using the APC.COM formula:
